Work about to start in St Nick’s Covered Market, Bristol!

in ,

gcp has been working with a fantastic team at Bristol City Council to reimagine the central area of the Grade 2* Listed Covered Market in the highly popular St Nicholas Markets.

The Covered Market has not enjoyed the same footfall as other parts of the market; the scheme therefore provides a new destination to encourage visitors to experience the market in its fullness.

The scheme plays with structure, materials, and recesses to create a finely balanced proposal which achieves both commercially viable floorspace and breathing space to a previously cramped site.

Our Declaration of Carbon Neutrality

in

Reducing our environmental impact has always been a key consideration in our design work. From delivering the UK’s first BREEAM Excellent sports centre in 2000, to becoming Passivhaus certified in 2007, and most recently generating whole life carbon assessments in 2019.

We are used to talking the talk, but in 2023 we decided it was time to walk the walk. Through our Employee Council we floated the idea of measuring our own carbon impact with a view to reducing carbon emissions as far as possible and becoming carbon neutral.

We reviewed various certification schemes and assessment methodologies including B-Corp, PAS 2060 and EcoVadis. The pros and cons were discussed in the Employee Council before a report was prepared for the Board. We settled on PAS 2060 as our methodology for measuring carbon emissions, creating a carbon reduction plan, and offsetting.

We can now release our Declaration of Carbon Neutrality for 2022-2023.

During this time, we reported on our Scope 1 and Scope 2 emissions, alongside Scope 3 emissions for transport. Scope 1 relates to on-site emissions, e.g. gas boilers. Scope 2 relates to off-site emissions for energy used on-site e.g. electric boiler. Scope 3 covers all other emissions on and off site including relevant upstream and downstream emissions.

Our total carbon footprint for 2022/23 was 6.2tCO2e, split into 44% Scope 2 and 56% Scope 3 emissions.

Over our historic reporting period our Scope 2 emissions have reduced year on year due to:

  • Installing an efficient HVAC unit with heat recovery to reduce carbon emissions through ventilation as well as improving office air quality.

  • Changing all office lighting to better performing LED fittings.

  • UK grid decarbonization.

In the same period our Scope 3 emissions fell sharply due to COVID, but also due to:

  • Encouraging staff to cycle where appropriate to reduce travel emissions.

  • Reducing the number of on-site meetings where not necessary.

  • Encouraging low carbon transport methods where possible.

Whilst 2022/23 saw an increase in Scope 3 emissions from 2020/21 and 2021/22 this is primarily due to an increase in staff numbers alongside business returning somewhat to the pre-COVID norm. Ignoring the impact of COVID, our Scope 3 emissions have reduced by 46% from our 2018/19 base level. This is demonstrated by the graph below.

Whilst we continue to reduce our carbon emissions, there will always be a need to offset the remaining emissions to achieve carbon neutrality. As such from 2022 we started a tree planting program.

Initially our tree planting was based on a will to do the right thing rather than data, but now we report against PAS 2060 we are monitoring how many trees should be planted annually to cover our emissions.

Our offsetting strategy is based on Pending Issuance Units (PIUs) for predicted growth of saplings rather than Woodland Carbon Units (WCUs) which cover sequestered carbon in mature woodland. gcp will monitor the survival rate and growth of the trees over the next reporting period to accurately monitor the carbon absorption.

In February 2024 gcp planted 160 trees to offset our carbon emissions for the 2022/23 reporting period. This equates to approximately 160 tonnes of carbon over the lifetime of the trees. This is far greater than what was required to offset our 6.2 tonnes of carbon emissions for the reporting period, but overachieving with PIUs allows us to achieve a real-world carbon break even point as soon as possible.

This is demonstrated in the graph below:

This demonstrates our predicted carbon emissions over the next 30 years against the real-time carbon offsets through tree planting. We can forecast that from the start of our reporting period we will be carbon neutral by 2044.

Extrapolating this in both directions, which includes a lot of assumptions, we can approximate that gcp will be carbon neutral for all emissions since conception in 1987 by 2061.

The Value of Competitions: Midland Road | Bristol

in ,

Background

In July 2023, Brighter Places in partnership with the Bristol Housing Festival launched a design competition, for a new affordable development within Bristol City center.

Midland Road is a prominent local centre, adjacent to Old Market and previous home to a paintworks, since demolished. The brief was to provide a 100% affordable / social rented development of up to 70 units.

Having previously worked with Brighter Places, our aim was to create both a destination location within the wider local community, and a design that sensitively responds to its local context and needs.

Process

For this scheme an understanding of local and broader contexts was key. We began by reviewing the typology and scale of the surrounding environment, the sites’ access to green spaces and the overall local transport links.

From this we recognized that Midland Roads presents a unique focus point of transport links, creating an idealized meeting place for residents & passers alike, with opportunity for commercial / community led interventions.

Similarly, our initial studies identified a lack of local green space links (both public and private). These spaces are critical to community growth & function, as such the provision of accessible green space was critical to the design.

Understanding the immediate context was also key. Surrounding structures presented a high density of 5+ stories, with a mostly industrial context, infilled with more modern midrise housing developments.

Our initial Massing would follow the relatively limited footprint of the site, whilst cutting out key foot / cycle connections to permeate the structure and allowing for a central courtyard to create meeting and commercial opportunities.

Looking at the opportunities & constraints available to us, we quickly identified 3 key strategies to develop:

  1. Green Spaces for all: green spaces are often a luxury in urban centers. Our aim was to create a mixture of both public and private green spaces within the scheme, by using the roofs as interconnected terraces to create over 900sqm of space for residents & a ground floor courtyard for the public.

  2. Fostering Community: modern housing often lacks community, with disconnected structures and sterile circulation. Our aim was to create a winding path laced with social spaces throughout the structure that then further connected to proposed green spaces. The aim was to create an interconnected set of communal streets to enhance interaction.

  3. Activated Streets: The site is uniquely located at the intersection between transport links, from foot to local buses. This presents the opportunity to create a local hub, the proposal would need to be open in nature, with ground floor uses that would encourage residents and non-residents alike inside.

The Design

The final design appeals to the industrial character of the site, using an exposed frame with infill patterned brick panels. The mass is broken down by circulation cut through’s at ground level, and circulation at upper levels, conjunction with the perforated forms of the flats this gives the structure a high degree of permeability. The structure itself steps down with the context, beginning with 10 stories, gradually reducing to 6 stories.

Starting at the ground level is a mixture of public courtyards and commercial units, moving up the structure is a winding path of private roof gardens & circulation paths, each flat within the block has to move up or down a maximum of one storey to access a green space.

Each flat has its own balcony, and by mixing walk up and same storey accesses, there is only a singular circulation corridor per 2 levels of flats, maximizing social opportunities to shared areas.

 

The Submission

The final design was submitted in August. Unfortunately, gcp were not selected for the final shortlist this time. Designing a dense urban proposal in the center of Bristol was both invaluable and enjoyable; an experience that we can take with us into future projects.
